Are Your Linux Files as Secure as They Should Be?

When it comes to Linux file security, most users are familiar with the basics—chmod, chown, and maybe even a quick glance at ls -l. But these simple tools are just the surface.

If you’re managing servers, deploying applications, or handling sensitive data, you need a deeper layer of protection. Linux offers powerful built-in tools that go beyond basic permissions—and understanding them is crucial.

In our latest guide, we break down the three core models of Linux access control:

  • Discretionary Access Control (DAC)
  • Access Control Lists (ACLs)
  • Mandatory Access Control (MAC)

Plus, we walk through how AppArmor, SELinux, and Auditd work together to secure your system from the ground up.
